Nga rereke e whakaaetia ana mo te taumaha me te rahi

1. Te Diameter o waho-I runga i te inenga porowhita ±0.5% o te diameter o waho kua tohua.

2.-O-o-te-Roundness-Rerekētanga i waenga i nga diameter nui me te iti o waho.

3. Tirohanga-Whakamahia te 10 ft (3m) arai tika kia piri nga pito e rua ki te paipa, 1/8 inihi (3mm).

4. Matotoru-Ko te iti rawa o te matotoru o te pakitara i tetahi waahi o te paipa kaua e neke ake i te 0.01 inihi (0.3mm) i raro i te matotoru ingoa kua tohua.

5. Ko nga roa me nga pito kore miihini me uru ki roto -0+1/2 inihi (-0+13mm) o tera kua tohua.Ko nga roa me nga pito miihini ka rite ki te whakaaetanga i waenga i te kaihanga me te kaihoko.

Nga Whakamatau Miihini mo te ASTM A671 LSAW Carbon Steel Pipe:

Te Whakamatau Whakamatau—Ka tutuki nga ahuatanga o te taarua whakawhiti o te hononga paiherea ki nga whakaritenga iti mo te tino kaha o te pereti kua tohua.

Whakamatau-a-arahi-Weld-piko - Ka whakaaetia te whakamatautau piko ki te kore he kapiti me etahi atu hapa e neke ake i te 1/8 inihi (3mm) ahakoa he aha kei roto i te whakarewa whakarewa, i waenga ranei i te whakarewa me te whakarewa turanga i muri i te piko.

Whakamātautau Whakairoiro-whakairoiro-Ko te roa o ia wea o te karaehe X1 me X2 ka tirotirohia ma te reo irirangi i runga i nga whakaritenga o te Waehere Paera ASME me te Waehe Pehe, Wāhanga tuawhitu, kōwae UW-51.
